Abstract

The long-unknown crystal structure of Bi-III has been solved. It comprisesa body-centend-tetragonal (bct) "host" and a bet "guest" component made upof chains that lie in channels in the host; the guest is incommensurate with the host along the tetragonal c axis. Diffraction data for Sb-II reveal that it too can be fitted with the same composite structure. The structuresof these two high-pressure phases of Bi and Sb are similar to those reported recently in the alkaline-earth metals Ba and Sr.
